4 mm longis; corollae lobis late triangularibus, acuminatis, cir- 
citer 6 mm longis, alte connatis, indus dense papillosis, apice 
leviter reflexis; coronae lobis coriaceis, oblongo-ovatis, 5 mm 
longis, acuminatis vel acutis, patentibus, apice leviter retusis, 
subplanis. 
A scandent shrub, entirely glabrous except the inflorescence, 
the branches subterete, rather pale when dry, about 3 mm in dia- 
meter, the internodes up to 20 cm in length. Leaves opposite, 
fleshy, when dry coriaceous, pale and shining on both surfaces 
and more or less wrinkled, oblong to oblong-obovate, 10 to 14 cm 
long, 3 to 5 cm wide, base obtuse, apex distinctly acuminate; 
lateral nerves pinnately arranged, indistinct, about 6 on each 
side of the midrib, ascending, scarcely more evident than are the 
lax, indistinct reticulations; petioles about 1 cm long. Umbels 
many-flowered, 8 to 9 cm in diameter, the thickened rachis about 
4 mm in diameter above, the pedicels spreading, slender, about 
‘3.5 cm long, sparingly appressed-pubescent. Flowers fragrant, 
about 1.8 cm in diameter, brown when dry. Calyx-segments 
oblong-ovate to ovate-lanceolate, acute or subacute, externally 
somewhat pubescent, about 4 mm long. Corolla-lobes broadly 
triangular, about 6 mm long and wide, spreading, rotate, exter- 
nally glabrous, internally densely papillose, the acuminate apex 
somewhat recurved. Corona 10 to 12 mm in diameter, stellate, 
the lobes spreading, coriaceous, brown, shining, oblong-ovate to 
ovate-lanceolate, acuminate, about 5 mm long, the external tip 
slightly retuse, the internal one ascending, the upper surface 
plano-convex and somewhat keeled in the median portion.

The alliance of this species is with Hoya luzonica Schltr., from which 
it is readily distinguished by its larger flowers, its pubescent pedicels and 
sepals, and its differently shaped, longer, acuminate, and slightly retuse 
corona-segments.
